FLY-TRAP.

SPECIFICATION forming part of Letters Patent No. 792,996, dated June 20, 1905.

Anplication filed October 11,1904. Serial No. 228.013.

To all 1117mm if mill y POW/(IP77!!! lie it known that I, Louis LACAILLIG, a citizen of the United States, residing at Butte, county of Silverbow, and State of ;\[ontana,

. l llZtVO lllYGntQtl it COI'tEllll new and LlSGfUl ll'llprovement in Fly-'llraps, of which the following is a specification.

My invention relates to a new and useful improvement in fl v-screens, and relates to that class of screens which will not only prevent the flies from entering the house, but also forms a trap for the flies or insects, so that the insects upon the interior or exterior of the screen may be imprisoned or disposed of at any time; and the object of my invention is to so construct a screen of this character that it will be extremely simple in construction, so that it may he manufactured at a comparatively small cost, while at the same time being durable and eflicient in action.

\Vith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which-- Figure 1 is a front elevation of my improved screen; Fig. 2, a plan view of the same; Fig. 3, a section taken on the line 3 3 of Fig. l.

A represents a frame which has two crosspieces B extending across from one side of the frame to the other adistance apart, and these cross-pieces are connected by strips C at the center and also a distance apart, so as to leave a square compartment D at the center of the screen.

E is wire-cloth secured around its eige upon each side of the frame A and covering the whole framework upon each side, except at the central compartment 1). This central compartment 1) is closed by a pane of glass F, which is arranged midway between the two sides of the cross-pieces B and strips C, as shown in Fig. 3. Thus there is a space left between the wire-cloth upon all sides of the central compartment 1).

Gr represents small tubes which connect the central compartment 1) upon each side of the glass F with the space between the \vire-clotl'is su rround ing the central compartment. These tubes (.nr extend quite a distance into the space between the wire-gauze, and each of said tubes is tapering, the smaller ends being upon the space between the wire-cloth. Thus any insects upon the screen will be naturally attracted to the central compartment l) on account of the glass pane within the same and when in the compartment I) will try to enter or escape through the tubes (1 and they will readily pass into the large r end ofsaid tubes, and so on into the trap formed bythe space between the wire-cloth, and their escape from said trap is prevented on account of the inner ends of the tubes being so small, and when desired these insects can be disposed of or allowed to escape through the openings H, formed through the frame A, these openings being normally closed by the caps or covers I. The crossstrips B are perforated at the desired points, as indicated at B, to allow the insects to pass from the space in between the strips B to the outer space, so that they may pass through the openings l-l Of course I: do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1. In a screen of the character described, a frame, wire-cloth secured around its edge to each side of the frame, a frame arranged within the center of the screen, said frame extending from one wire-cloth to the other so as to leave a compartment upon the interior of this supplementary frame, the wire-cloth being cut away and not covering this compartment, a pane of glass arranged within this compartment midway of each side of the frame, openings extending through the supplementary frame and communicating with the space between the wire-cloth surrounding the supplc inentary frame, said tubes extending from each side of the pane of glass and beingsmaller upon their inner ends, the outside frame provided with openings closed by suitable movable covers through which the insects may be removed, as specified.

2. In a screen of the character described, an outer frame, an inner frame arranged within the outer frame so as to leave a compartment within the inner frame, two sheets of wirecloth, one arranged upon each side of the frames covering all of the screen except the compartment within the inner frame, a pane of glass arranged within the inner frame and midway between the two sides of the frame, tubes extending from the compartment upon each side of the pane of glass into the space between the wire-cloth surrounding the inner frame, said tubes extending into said space a considerable distance, said tubes being tapering, their larger ends opening into the compartment, the outer frame provided with openings formed through the same extending from between the wire-cloth to the exterior of the frame, movable covers normally closing said openings, as and for the purpose specified.

3. In a screen of the character described, an outer frame, two cross-pieces extending across between one side of the frame to the other, two strips connecting said cross-pieces so as to leave a compartment bounded by the crosspieces and the two strips, two sheets of wirecloth securedsto the outer frame and also to the cross-pieces and strips but not covering said compartment, a pane of glass located in said compartment and midway between the two sides, tapering tubes extending from said compartment upon each side of the pane of glass through the cross-pieces and strips a distance into the space between the wire-cloth,

the larger ends of said tubes opening into the compartment, the cross-pieces provided with openings formed therethrough between the Y wire-cloth, the outer frame provided with openings formed therethrough extending from the space between the wire-cloth to the exterior of the frame, and movable covers normally closing said openings .upon the outside, as specified.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
